• What is the cause and solution for SAP error message C1079 - Allowed values are not consistent ?

  The SAP error message C1079, which states "Allowed values are not consistent," typically occurs in the context of configuration settings, particularly when dealing with characteristics and values in the SAP Variant Configuration (VC) module. This error indicates that there is a mismatch or inconsistency in the allowed values defined for a characteristic in a configuration profile.
  Cause:
  
  
  Inconsistent Allowed Values: The allowed values for a characteristic may not be properly defined or may conflict with other characteristics. For example, if a characteristic is defined to have certain allowed values, but those values are not consistent with the values defined in the dependent characteristics, this error can occur.
  
  
  Missing Dependencies: If there are dependencies between characteristics that are not correctly set up, it can lead to inconsistencies in the allowed values.
  
  
  Incorrect Configuration Profile: The configuration profile may not be set up correctly, leading to conflicts in the allowed values for the characteristics.
  
  
  Data Integrity Issues: There may be issues with the data integrity in the master data, such as missing or incorrect entries in the characteristic values.
  
  
  Solution:
  
  
  Review Characteristic Definitions: Check the definitions of the characteristics involved. Ensure that the allowed values are correctly defined and that there are no conflicts between them.

  Configuration Profile Review: Review the configuration profile to ensure that it is set up correctly. Make sure that all characteristics and their allowed values are included and correctly defined.
  
  
  Data Consistency Check: Perform a data consistency check to identify any discrepancies in the characteristic values. This may involve checking the master data for the characteristics and their allowed values.
  
  
  Testing: After making changes, test the configuration to ensure that the error no longer occurs. Create a new configuration or modify an existing one to see if the issue persists.
